Kilogram
Definition: A kilogram (symbol: kg) is the base unit of mass in the International System of Units (SI). It is currently defined based on the fixed numerical value of the Planck constant.
History/origin: The kilogram was introduced during the French Revolution in 1795 as part of the metric system. Initially defined as the mass of one liter of water at its freezing point, it was later refined for greater precision. In 1875, the Treaty of the Meter established the International Bureau of Weights and Measures (BIPM) to standardize measurements, including the kilogram. The definition of the kilogram was updated in 2019 to be based on the Planck constant rather than a physical object.
Current use: As a base unit of SI, the kilogram is used globally in nearly all fields and applications, with some exceptions in countries like the United States.
Milligram
Definition: A milligram (symbol: mg) is a unit of mass in the metric system. One milligram is equal to one thousandth of a gram.
History/origin: The milligram was derived from the gram when the metric system was established in France in the late 18th century. It was introduced to measure very small quantities accurately.
Current use: Widely used in medicine, pharmacology, and scientific research for precise measurements of small masses.
